| Abstract | ||||
| In this investigation, the flow of an incompressible viscous fluid driven by the travelling waves along the boundaries of a symmetric channel is studied when inertia and streamline curvature effects are not negligible, where the flow of / blood nanofluid and (Cu– ) / blood hybrid Nano fluid has been employed to investigate the behaviour of flow and heat transfer. An asymptotic solution is obtained to second order in the wave number, a ratio of channel width to the wavelength, giving the curvature effects. A domain transformation is used to transform the channel of variable cross section to a uniform cross section, and this facilitates in easy way of finding closed form solutions at higher orders. The relation connecting the pressure gradient and time rate of flux is obtained. The analysis also includes three different shapes of copper Nano-composites, namely, platelet, cylinder and brick- shaped. The impact of various embedded parameters on the flow and heat transfer distributions have been demonstrated through the graphs. All the flow properties, temperature profile and rate of heat transfer at the walls are greatly influenced by the presence of copper nanoparticles. Furthermore, it was observed that the platelet shaped Nano-composites provide a better heat transfer ability as compared to the other shapes of Nano-particles. The effects of inertia and curvature on pumping, trapping and shear stress are discussed for symmetric channels and compared with the existing results in the literature. | ||||
